In various countries of the world like India, after 1990, the shortage of land for construction purpose has become a problematic issue, particularly in Jammu and Kashmir, where horizontal growth has reached its peak level. Now days the new construction is mostly done on weak soil. Thus it became necessity to improve the strength of the soil at the construction site. This paper describes the suitability of using coal ash with lacustrine soil for increasing its shear strength and CBR properties, and to utilize the coal ash being a waste product which otherwise needs to be disposed to the environment causing environmental pollution. Several civil engineering laboratory tests were conducted to study the strength gain when coal ash was mixed with local soil sample. The soil was replaced by coal ash as 10%, 20%, 30%, and 40% by weight. These soil specimens were tested for compressive strength and CBR value for 7 days of age and were compared with normal soil sample without mix. The tests indicate an improved strength and better CBR properties of soil sample when stabilized.
